摘要

Growth and structural changes in ponderosa pine (Pinus ponderosa) stands a 25-year posttreatment period to determine the impacts of a combined stripcut-thinning treatment. Trees on one-third of a watershed in north-central Arizona had been removed in clear-cut strips. Trees in the 'leave' strips were thinned. Number of trees, basal area, and volume growth have increased since the leave strips were thinned and will likely continue to increase as the residual trees increase in size. Integrity of these stands should be maintained in the future, although it might be necessary to plant ponderosa pine seedlings to reestablish a forest cover in the cut strips for timber production. A more likely scenario is to manage the watershed for other multiple-use values obtainable from ponderosa pine stands.
